Development of an adaptive diffserv-based mobility management approach for enhancing QOS within network mobility (NEMO) /
Quality of Service (QoS) is defined as the capability of network elements (e.g. application, host and router) to provide some sort of assurance and service differentiation for consistent network data delivery.

| 520 | |a Quality of Service (QoS) is defined as the capability of network elements (e.g. application, host and router) to provide some sort of assurance and service differentiation for consistent network data delivery. Internet Engineering Task Force (IETF) has endorsed Network Mobility Basic Support (NEMO BS) protocol (RFC 3963) to address the challenges of the entire network mobility (such as the movements of trains, buses, ships and aircrafts). However, NEMO BS is designed without QoS support in mind. Similar to MIPv6, it can hardly offer same level of services (i.e. Best-Effort) to all the users without obligation to the applications needs. This poses a problem to real-time applications that required certain level of QoS commitment. Moreover, delays in data delivery, packet loss and higher signalling overheads are likely to transpire because of suboptimal routing and multiple encapsulations of data packets. Incorporating QoS with mobility support seems to be needed to fulfil the necessity of users in mobile network. This thesis proposes a new scheme that deploys Differentiated Service (DiffServ) QoS-based model to achieve smooth delivery of real-time traffic in heterogeneous mobile networks. Furthermore, the proposed scheme uses the mechanisms of Fast Hierarchical Mobile IPv6 (FHMIPv6) to reduce location update signalling issues, since the MR doesn't concern about local and global moventment. It also conquers the weakness of NEMO inefficient routing by utilizing the methodology of MIPv6 route optimization to bypass the HA and catering optimal path. The feasibility of the proposed scheme is evaluated using two methods namely, simulation (i.e. NS-2) and analytical approach. The performance of proposed scheme is benchmarked with the standard NEMO basic support protocol. Eventually, the simulation results reflect that the proposed scheme outperforms the standard NEMO BS protocol by alleviating the packet loss and diminishing the handover latency, even though when the velocity of mobile router reached up to 90 Km/h. On the other hands, the analytical results show that the proposed scheme obtained noticeable performance improvement by reducing the signalling cost when the network size is increased. | ||
